This apartment had by far the best internet I have used in Bangkok. It was the first one (out of now 5) I have stayed in that I had no problems at all. So if internet is super important then this is your place.
Beyond that the apartment is very spacious and well laid out. There is lots to do and see in the area. A villa market for groceries is a short walk away. Motorbike taxis near by, and about a 6 minute walk to the sky train. I definitely recommend this place.
